A Thai woman who delivered six children this May has named them after her favourite car brands -- Audi, Fortune (Toyota Fortuner), Porsche, Mini, Volkswagen and Fiat, the Bangkok Post reported.

The sextuplets -- three girls and three boys -- are the first born in Thailand.

Duangchanok Wangwitthayaskul, 29, had pregnancy related problems and could not have children for a long time.

But when she delivered the babies at Bumrungrad International Hospital at the beginning of May, Wangwitthayaskul along with her husband decided to wait for two months to show the infants in public.

According to a Thai tradition, in addition to the names recorded in birth certificates children are given pet names that often replace the name in informal situations, in family and with friends throughout life.

But this couple opted to choose their newborns' nick names from car brands.

Duangchanok's pregnancy was the result of in vitro fertilisation. After the birth of six children, the parents had to invite relatives to help care for children and hire three nannies.
